How do I test turn signals that aren’t working with an ohm meter?
Always give year, make, engine size and model # when asking questions. Nothing is the same.
-To check the bulbs – rx1 – one test lead to ground (metal side of bulb). The other test lead to positive (end of bulb). If it’s good – very little resistance.
-When tesing for open circuits (not making connection) rx1 = 0 is good connection.
-To check if socket has a good ground – rx1 – One test lead to inside edge of socket. The other lead to ground on vehical.
-To check if positive of socket is good – rx1 – With key off. One lead to inside center of socket. The other lead to connector of wire harness.
-Anything after that, it’s wire diagram time. Buy a shop manual.
-rx1 checks for continuity. When there are no breaks in the circuit, resistence = zero.
-Check continuity from the turn signal switch to the bulbs (key off).
-Check for continuity from flasher relay to turn signal switch (key off).
-Check for battery voltage to flasher relay (key on).
-If every thing checks out so far, with the key on and signal switch pushed L or R, you should feel the flasher relay click on and off.
-Don’t forget to check the turn signal fuse.
